The precise behaviour of this program in certain circumstances has changed.
This will continue to occur until it is considered "finished".

Any writes to the file while e2compress is in action (that is to say
after e2compress has read the file but before the file is replaced with
the compressed version) are lost. (For decompressing, no writes are
possible because the EXT2_NOCOMPR_FL flag is set on the input
file, which prevents any other processes from having the file open.) In
both cases (compressing and decompressing) the results of ,any
`chmod', `chown' or `touch' operation during this period`
will be lost.
